2 Important Information

2.1 Safety instructions
When carrying out work on the heating sys-

tem, such as cleaning and maintenance, wear
appropriate protective equipping when re­quired.
There is a danger of getting injured through:
burning, knocking against corners and edges,
crushing in moving parts and noise.

Mains supply: 400V C

In a risky situation, the PYROT can be discon­nected from the electrical mains at all the leads by
the master switch on the control cabinet

Doors

CAUTION
FIRE HAZARD:
The boiler plant must never be operated with
the doors open! Red-hot objects that might
escape could result in fires.

RISK OF INJURY:
If the doors are open during operation, sparks
or flames could leap out.

Equipment for dissipating excess heat

The operational reliability of the thermal run-off
safety valve should be examined annually by a
competent specialist. The safety heat exchanger
must not by any means be used as an operational
heat exchanger.

Seals

For the functioning and controllability of the
burner, it is important that no unwanted air can
leak in, entering unchecked through leaky spots.
The doors and lids have to shut tight − any dam­aged seals must be replaced immediately.
Tighten the retaining screws and handles snugly.

Operation, cleaning & maintenance

Bear in mind that only if operated and maintained
properly can even the best of products fulfil their
functions well, doing so for a long time and free of
malfunctions.
Compliance with the "Cleaning" section is manda­tory!

2.2 Excess temperature/power failure

CAUTION
DANGER OF THIS SUDDENLY GOING UP IN
FLAMES:
Do not open the doors or lids on the boiler
plant!

- Switch on additional heat consumers.

- The exhaust fan goes out of operation.

- The temperature-limiting safety switch triggers.

- The valve for the thermal run-off safety valve

opens at approx. 95°C. The excess heat is
conducted off into the channel.

If the temperature-limiting safety switch
(TLSS) has triggered, then it has to be manu­ally unlocked. The TLSS is situated at the top
of the boiler.

To reset, unscrew the black cap and press the
button.
NOTE:

Only as of a temperature of approx. 70°C

resetting is possible.
Possible causes for excess temperature:

- Incorrect setting on the control module.

- Defective component of the system (pump or

valve).

- Sudden drop in output to zero. The feed auger
still has to be emptied. The heat yet produced
by this can result in surplus temperature. Acti­vate "DISSIPATE SURPLUS HEAT" function!

2.3 Low water/excess water pressure

Possible causes:

1. Low water: Leakage in the heating system.

2. Excess water pressure: The expansion system
not functioning.

In either case, one should have the facility exam­ined by a competent heating installer.

Unlock this malfunction with either the reset
button for the water level control system or for
the overpressure monitor, and by pressing the
OK key on the control panel.

6

2.4 A fire hazard

With insertion-type firing systems, the conveying
route creates a connection between the silo and
the burning material in the boiler plant.
With the PYROT insertion-type heating boiler, the
feed auger is also the metering auger, and is thus
always filled up with material during operation
There are various safety devices provided to pre­vent burn-back.

Temperature sensors:
By means of temperature sensors on the feed au­ger, in case of excess temperature the loading to
the feed auger is interrupted, and the feed auger's
material is inserted into the combustion chamber.

Slide valve (optional):
This closes in case of a standstill, danger of burn­back or power failure (spring return motor).

Rotary valve (optional):
Instead of a slide valve, in silos with pressurisa­tion.

Drop-off route:
A vertical drop-off section interrupts the con­nected line of burning material.

Fire-extinguishing system (option):
This system, which functions independently of the
electrical power, brings about a flooding of the
material to be burned that is located in the feed
auger. The activation temperature is approx.
95°C.

2.5 Wood fuels, minimum requirements

The PYROT is only suitable for incinerating the
fuels listed in Spec Sheet 1010 "Minimum Re­quirements for Wood Fuels" (see supplement).

If different fuels are used, KÖB will not as­sume any liability for the functioning or ser­vice life of the boiler plant. Refer to the "War­ranty" section in the General Terms and Con­ditions of Delivery.

2.6 Filling the fuel storage unit

2.6.1 By dumping

Rotary sweep extraction and spring-operated
extraction

Heating system in operation:

- If the articulated arms or spring-mounted
plates are still covered by fuel

, refilling can be

carried out immediately.

- If the articulated arms or spring-mounted
plates are no longer covered by fuel

, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. As
soon as the articulated arms or spring­mounted plates have retracted through a re­quest for material, the refilling can be contin­ued.

Heating out of operation

:

- If the articulated arms or spring-mounted
plates are still covered by fuel

, refilling can be

carried out immediately.

- If the articulated arms or spring-mounted
plates are no longer covered by fuel

, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. Then
activate the "SILO FILLING" function. To do
so, press the LOADER SYSTEM key (F4) and
then the left arrow key (<). Then select "YES"
and confirm with "OK". Wait until the articu­lated arms or the spring-mounted blades go
under the cup washer, and then finish evenly
filling the silo. The "SILO FILLING" function
brings about the filling of the fire box.

NOTE: The "SILO FILLING" function cannot be
activated until the heating system has been
out of operation for one hour.

Moving floor conveyor

- Fuel can be refilled automatically.

Funnel extraction system

- It is mandatory that the heating system be in
operation!

2.6.2 By blowing in

The heating system has to be out of operation
(danger of excess pressure or negative pres­sure caused by the action of blowing-in). Fill­ing procedure as described in section 2.6.1.

2.7 Correcting malfunctions in the feed sys-

tems

The cause of motor malfunctions in feed systems
is usually clogging by large pieces of wood or for­eign matter.

CAUTION
DANGER OF INJURY:
Always turn off the master switch before car­rying out any repair of a malfunction on feed
systems and every time before a maintenance
lid is opened or a protective device is re­moved!

The automatic operation of the system makes it
impossible to foresee the time point when the
conveying equipment will switch on.

4 Commissioning/Operation

4.1 The initial start-up

The initial start-up is carried out either by KÖB
Holzfeuerungen GmbH or a competent individual
named by it.

Be absolutely sure to follow the instructions in
the Assembly and Installation Instructions. No
guarantee may be claimed for damages in
cases of initial start-ups carried out improp­erly at one's own initiative.

First check:

- Is there enough water in the heating system?

- Has the heating system been bled of air?

- Are the slide valves open for the heating-

system's forward and reverse flow?

- Can enough fresh air get into the heating
room?

- Empty ash bin.

- Are the doors and lids on the burner all closed

leak-tight?

4.2 Operation

4.2.1 Heating up

- Press the F1 key "PYROT Wood". The loader
modules will be switched on in the appropriate
order. When there is enough fuel in the com­bustion chamber, the entire loader system
switches off.

- The automatic ignition then takes place. The
ignition process stops as soon as the fire is
started.

4.2.2 Operation

- The material is supplied depending on the light
barriers in the metering container and in the
combustion chamber, allowing for the residual
oxygen.

- The primary and secondary air vents change
their positions depending on the exhaust gas
temperature and residual oxygen.

- Using the setting "Storage Management, Tem­perature, Storage, Average", it is possible to
keep the facility in continuous high­performance operation for as long as possible
– with fewer ignitions, better efficiency and lo­wer emissions.
(Only possible with accumulator option)

- When the boiler temperature set is reached,
the facility switches to "Run Auger Empty".
When the feed auger has been run empty, and
the exhaust gas temperature is less than 90°C,
the exhaust gas fan switches off and the air
vents close.

- When the "System Temperature Setting" is
fallen short of, the facility is automatically star­ted back up.

4.2.3 Switching off

- Press the F1 key "PYROT Wood". As feed­back to this, "Run Auger Empty" will appear on
the control panel.

CAUTION: Do NOT use the master button to
switch off (DANGER OF BACK BURN) !!!

5 Oil burners on a Pyrot

Be sure to note:

- The oil burner's firing power may amount to a
maximum of 70% of the rated heat output in
wood-burning operation.

- The selection of the oil burner as well as the
actual nozzle length have to be determined by
the supplier of the oil burner.

- Only either wood-burning operation or oil­burning operation is possible.

- For wood-burning operation, put in the sealing
plug.

- Close the flue gas recirculation system.

- Set the speed of the exhaust fan such that the

flame only reaches halfway up the fireclay­lined flame tube.

6 The ECOTRONIC control system

6.1 General information

The ECOTRONIC facility control system is a de­centralised microprocessor system (CAN-BUS)
developed by KÖB with various modules that are
connected by a data transmission line.

Its function

The ECOTRONIC records all the data relevant to
operation and controls the supply of and demand
for heat.
Thus the boiler plant is continuously monitored
during all the operating phases and kept within an
optimum range in terms of emissions.

Factory settings (pre-settings)

All the parameters in the ECOTRONIC, such as
set point values and switching times, are pre-set
and can be called back up at any time. The fig­ures for the factory settings are given in brackets
for the various parameters.

6.1.1 Replacing the battery

There is a battery built in beneath the removable
lid on the control module (type: Panasonic Lith­ium BR2330). It is for buffering the time, date and
settings.

- The battery needs replacing every five
years!

- Do not disconnect the mains voltage while
changing the battery (do not turn off master
switch)!

6.4.2 Utility water heater
Function:

- ECO-B1
When the temperature of the utility water
drops, it is reheated by the built-in heat ex­changer from the heat accumulator (hydraulic
switcher). The condition for this is a relevant
difference in temperature (choice of control
according to temperature difference or fixed
temperature).
The heating periods (daily and weekly pro­grammes) can be set using the integrated
timer.

- ECO-B2

When the temperature of the utility water
drops, it is reheated by the built-in heat ex­changer from the heat accumulator (hydraulic
switcher). The condition for this is a relevant
difference in temperature (choice of control
according to temperature difference or fixed
temperature).
The flow rate of the heating water is controlled
by the return temperature (quantity control).
This produces optimum storage stratification
with long-lasting high temperature on the stor­age unit flow pipe.
The heating periods (daily and weekly pro­grammes) can be set using the integrated
timer.

Operating modes:

- Off:
The utility water heating system is switched off.

- Timer:
Utility water heating following clocked pro­gramme. (The boiler is only warmed up during
the heating period.)

- On:
The boiler is heated up when prompted for
heat and when there is sufficient system tem­perature.

6.4.7 Solar

Function (ECO-S1):

This is used in simple solar systems with a single
control circuit to heat the utility water in the solar
utility water heater (Art. No: WSS-___). The
ECO-S1 controller is an additional component for
the ECO-B1(2) controller for the utility water
heater. When the solar collector is hotter than the
utility water at the bottom, it is heated up by the
solar collector.

(10) Operating hours counter

Function (ECO-S3):

(Only possible with accumulator option)
This is used in large solar systems to heat the util­ity water in a solar utility water heater (Art. No:
WSS-___) and for supplying heat to the heat ac­cumulator by means of a triple control circuit. The
first circuit is for heating the domestic water, the
second circuit is for heating the heat accumulator
at the back/bottom and the third circuit is for heat­ing the heat accumulator at the front/top. The
heating storage unit is heated up by an externally
situated plate-type heat exchanger. On switchover
from utility water heater to heat accumulator, the
secondary pump is switched on, which is then in
operation with the solar pump. For optimised func­tioning, the flow rate in the secondary circuit has
to be adapted to the primary circuit (e.g. with flow
rate gauges in the primary and secondary cir­cuits).

7 Cleaning/Maintenance

7.1 Boiler
Regular cleaning and maintenance of the facility is the customer's most important job for years of

trouble-free operation and to obtain the greatest possible output with the best efficiency.
Here the cleaning intervals for chip material are listed as per ÖNORM M 7133 with clinging bark –

0.8% ash content. The cleaning intervals may vary, depending on the fuel, the amount of fine matter
and the operating method.

CAUTION – RISK OF INJURY: Before beginning cleaning work, put the facility out of operation. Be
absolutely sure to wear protective gloves, protective eyewear if required and use the cleaning uten­sils that come with the facility (danger of blow-ups, burns and getting crushed)!

After approx. 300 operat­ing hours:

Remove ash from the ex­haust gas collector.

After approx. 1000 operating hours:

Unplug the plug from the exhaust gas
fan, unscrew butterfly nuts, pull out mo­tor with impeller and clean with broom or
wire brush.

CAUTION: DANGER OF INJURY – be
absolutely sure to switch off master
switch.

After approx. 300 oper­ating hours:

Take off and clean light
barriers and inspection
windows on the firing
block.
Remove dust and ash de­posits in the openings.

With pneumatic pipe cleaning system, after
approx. 600 operating hours; without pneumatic
pipe cleaning system, after approx. 300 operat­ing hours:

Open boiler door and clean all the heat exchanger
pipes (9) with wire cleaning brush. Use the stoker
to carefully

draw to the front the fly ash lying in the

rotation combustion chamber (8).

IMPORTANT

:
With pneumatic pipe-cleaning system, discon­nect the compressed air line before opening the
boiler door – danger of injury

!

After approx. 300 oper­ating hours:

Open lid across from
feed auger and clear the
slots in the grate (5).

After approx. 1000 op­erating hours:

Clean recirculated flue
gas line.

After approx. 100 operating hours:

Open ash pan doors and empty ash con­tainers.
With automatic de-ashing (optional)

Exhaust gas deduster, detached (optional)

IMPORTANT: Never operate the boiler without
ash container!

Pneumatic tube-cleaning system (optional)

- Operation and maintenance of the compressor
(optional) according to the manual that comes
with the facility.

- The timer that comes with the compressor is for
limiting the running time and should be
mounted between the compressor and the
power supply.

- When the compressed air system is provided
by the customer, the compressor has to be
suited for continuous operation or be secured
against continuous operation (e.g. timer for lim­iting running time).

- Continuous operation of the compressor indi­cates leakage in the air system. Check air sup­ply line and valves for leakage.

After approx. 1000 operating hours:

Unplug the plug, unscrew butterfly nuts, pull
out motor with impeller and clean with broom
or wire brush.

CAUTION: DANGER OF INJURY – be abso­lutely sure to switch off master switch.

After each cleaning of the set of tub­ing

Open lid and clean the guide blades of
the de-duster with hand-brush.

After approx. 300 operating hours (90­litre ash bin):

Empty ash bin beneath the de-duster.

Regularly drain condensation water in the
compressed air distribution bar.

7.1 Installing the displacement rods into the
heat exchanger

The displacement rods improve the heat transmis­sion in the heat exchanger and reduce the tem­perature of the exhaust gas, thus improving the ef­ficiency of the heating system. They are taken out
to clean the heat exchanger tubes and then put
back in.

Insert the displacement rods into the heat ex­changer tube with the thick end first. Push until
they are flush with the bottom of the tube. Tole­rance +/- 5 mm.

Remove the displacement rods with a pair of pli­ers, as shown below. The heat exchanger should
be cleaned at the intervals prescribed so that, on
the one hand, performance and efficiency are
maintained, and on the other, the displacement
rods can be easily removed.

7.2 Feed systems

All the geared motors on the feed systems are
maintenance-free.

- A change of lubricant and/or oil is recom-

mended every 20,000 operating hours or every
three years.

- Re-lubricate flange bearings and other lubricat-

ing points regularly with lithium soap grease.

- Check chain drives for wear and, if necessary,

tighten them up and lubricate with chain oil.

- Check all the bolts to be sure they are snug.

- Once a year check the extraction components

in the silo and/or bunker for damage and soil­ing. Remove any foreign matter there might be.

- Rotary sweep extraction system (AG)

- Check and lubricate elbow joints, pivot pins,

tension springs and tension chains. Readjust
elbow joints if necessary.

- Inclined extraction system (AP/APS)

- Lubricate the gasket between the extraction ca-

sing and the geared motor and universal joint
for the auger.

IMPORTANT: Never use inflammable lubri­cants!

8 Shutdown

Heating boiler

- Pipe-type heat exchanger:

When the PYROT is put out of operation for a
long period (such as for summer breaks), be
sure to carefully clean the pipe-type heat ex­changer with a steel brush required.

- Prevent high-temperature corrosion when chip-

boards are incinerated:
If the heating room is moist or there is any other
atmosphere that promotes corrosion (e.g. poor
ventilation, residual enamel near the heating
room, etc.), after carrying out the cleaning, also
spray the pipe-type heat exchanger with bio­diesel.

- If there is a danger of frost, empty the heating

system, following the heating installer's rules, or
have anti-frost agent filled.

Control system

Even when the PYROT is put out of operation for
long periods, the power supply to the control sys­tem should not be interrupted (do not turn off mas­ter switch).

Why?

- The "intermittent control system" switches the
consumer pumps on for five seconds every 24
hours. This prevents the pumps from jamming
during long standstills. This saves on expensive
repairs.

- Prevent the formation of condensation in the
lambda sensor.

- Extend the service life of the buffer battery.

9 Carrying out disposals

Shutdown

- If necessary, first switch off the PYROT using
the F1 or F2 key. When the burn-out has taken
place, and the burner has cooled off, turn off
the master switch.

- Disconnect the mains connection to the control
cabinet.

CAUTION DANGEROUS VOLTAGE!
Only licensed electrical firms are allowed to
disconnect and dismantle the connection to
the electrical network.

- Close the forward flow and return flow slide
valves.

- Open the drain tap on the bottom of the boiler
of the PYROT and drain water.

Only heating system installers may drain the
boiler and dismantle the connections to the
heating system.

- Disconnect the forward flow pipe and return
flow pipe from the PYROT.

Instructions regarding transport to a different
location

The personnel who carry out transports to different
locations have to know the dangers involved of ac­cidents that might arise in doing so and use suit­able measures to prevent such from happening.

Instructions regarding waste disposal

- Comply with customary laws and regulations on
disposing of waste.

- Contract a disposal firm to dispose of and recy­cle waste in an environmentally friendly fashion.

2007-09-12_E

A prerequisite for approval is the express permission for such by the public authority responsible. For claims to
the warranty according to Section 11 of our General Terms and Conditions of Delivery, wood fuels have to meet
the following conditions. If those conditions are not met, then approval is possible with restrictions (warranty,
maintenance, operational safety) with a written statement by the manufacturer in reference to the facility.

1) Non-combustible substances contained

No wood fuels may contain any foreign bodies, such as pieces of metal, stones, masonry remnants or plastics. Nor
must the following limits (per kg of dry fuel) for non-combustible substances contained (ash analysed at a
temperature of 815°C) be exceeded or fallen short of:
Limit Comparison with untreated forest wood

1.1) Chlorine Cl: max. 300 mg/kg 10 mg/kg

1.2) Sulphur S: max. 1000 mg/kg

120 mg/kg

1.3) Total Cl, S: max. 1000 mg/kg 130 mg/kg

1.4) Ash content, total: max. 15.0 g/kg 5.0 g/kg

1.5) Alkali oxides in the ash (K

2

O and Na2O): max. 1.0 g/kg 0.35 g/kg

1.6) Sintering point of the ash: min. 1000°C approx. 1200°C
Consequence of substantial overstepping of limits (1.1, 1.2, 1.3, 1.5, 1.6):
a) Hot-gas corrosion in the heat exchanger → Special maintenance instructions for heat exchanger
→ Shortened service life of heat exchanger
b) Early sintering and melting of the ash → Special maintenance instructions for firing,
→ Increased maintenance costs (firing, boiler door)
If the maintenance instructions are not followed, a process will be created that builds up in a negative fashion with:
→ Cinders change the airflow → Temperature peaks → more slag → etc, until there is fast destruction of the
refractory materials

1.7) Additives in remnant and used wood: Free of heavy metals and halogen compounds

2) Superfines & dust (wood particles smaller than 1.0 mm as per ÖNORM M 7133)

2.1) Without pre-dryer, max. 10.0% of the total mass; consequence of substantial overstepping of limit:
Temperature peaks → Slag formation → Even higher temperature → etc, to the point of destruction;
→ Special maintenance instructions for firing;
Elevated values are especially critical for remnant wood in combination with elevated values as per 1.1, 1.2

2.2) For forest wood chips with pre-dryer, max 4.0% of the total mass; consequence of substantial overstepping of

limit:
→ Moving the exhaust air lines → Special maintenance instructions for cleaning exhaust air line

3) Origin and treatment

3.1) Forest wood and plantation wood (complete trees and trunk wood untreated)

Mature wood from trunks and branches, untreated, chopped as billet wood or chips

3.2) Compressed wood, pellets (conforming to standards, such as: ÖNORM M 7135)

Untreated wood with limited bark content, compressed by machine and calibrated

3.2) Increased proportion of bark, tree cuttings from roadside trees (untreated)

Remnants from the forestry and sawmill industries or from conservation of the countryside (elevated ash
content).

3.3) Remnants from derived timber products

Usually a mixture of untreated and treated wood in the form of shavings from processing machinery and chips
from choppers that run slowly. In cases of elevated proportions of dust and/or limited storage volumes, these
shavings are compressed into briquettes.

3.4) Used wood

This is essentially untreated wood that has been used prior to its energetic utilisation (e.g. pallets). It is reduced
in size by shredders for thermal utilisation. The metal parts have to be removed afterwards (by magnetic
separators).

4) Particle size: adjustment of the conveyor augers

4.1) G30/G50 chips from untreated wood as per ÖNORM M 7133:

made by fast-running and cutting tools;
max. coarse fraction with cross-section and length

In automatically loaded boiler plants, the wood fuels that come to be used should be individually listed in offers and

orders as follows:
a) S 130 W10 to W20 G30/50 Sawdust, untreated (planing shop)
b1) S 200 W20 to W35 G30/50 Sawdust, untreated (sawmill)
b2) S 200 W20 G30/50 Forest wood chips, soft, untreated
c1) S 250 W20 to W35 G30/50 Forest wood chips, soft, untreated
c2) S 250 W35 to W50 G30/50 Sawdust, untreated (sawmill)
d1) S 300 W20 to W35 G30/50 Forest wood chips, soft/hard, untreated
d2) S 300 W35 to W50 G30/50 Forest wood chips, soft, untreated
e1) S 350 W20 to W35 G30/50 Forest wood chips, hard, untreated
e2) S 350 W35 to W50 G30/50 Forest wood chips, soft/hard, untreated
e3) S 350 W50 to W60 G30/50 Forest wood chips, soft, untreated
f1) S 400 W35 to W50 G30/50 Forest wood chips, hard, untreated
f2) S 400 W50 to W60 G30/50 Forest wood chips, soft/hard, untreated
g) S 130 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed
h) S 200 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed
i) S 250 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed
j) S 350 less than W15 G30/50 Briquettes from wood remnants D 40 to 60 mm
k1) S 650 less than W10 Pellets conforming to standards, untreated D 6 to 10 mm
k2) S 650 less than W10 Pellets conforming to standards, untreated D 11 to 15 mm

6) Maximum water content allowed, W, (percentage by weight of th e total mass)

The maximum water content allowed in the fuel when entering the furnace should be taken from the spec sheets for
the furnace series. With a pre-dryer installed between the furnace and the fuel storage site, extra water content can
be in the fuel stored (see specifications in reference to the order). The water content influences the maximum
furnace output possible, the heat emission required to the pre-dryer and thus the maximum heat emission possible
to the consumers.

7) Other information

7.1) Ash and cleaning

Untreated wood without bark has a proportion of ash less than 0.5% of the fuel mass supplied. All the
specifications regarding cleaning involved are based on untreated wood with bark attached with an ash amount
of 0.8%. The cleaning and maintenance involved for other wood fuels should be adapted according to the
amount, the specific weight and the behaviour of the ash.

7.2) Changing fuels

A great change in fuel quality, such as bulk density, water content, dust proportion or ash content might make a
manual correction of the firing parameters necessary (see Operating Manual).

8) Non-woody fuels from biomass

Non-woody fuels from biomass, such as needles, foliage, grain, straw, fruit pits, etc, are usually unsuited as fuel for
trouble-free operation and thus are not approved.
